MAJ-f Patented Sept. 24, 1935 UNITED STTES PATENT OFFICE SKATE ter, Mass., a corporation of Massachusetts Application June 21, 1934, Serial No. 731, 693 2 Claims. (Cl. 20S- 173) The principal objects of this invention are to provide means for accompanying Fig. 3 is a plan of a part of the toe piece of the skate removed from the other parts;

Fig. 4 is a sectional view on the line 6-4 of Fig. 1;

Fig. 5 is a plan of the shank removed from the rest of the skate;

Fig. 6 is a transverse sectional view on the line 6 6 of Fig. 5;

Fig. '7 is a longitudinal sectional View` on the line 1*? of Fig. 1 of the shank, on enlarged scale;

Fig. 8 isa similar View on the line 8 8 of Fig. l of the heel piece, on enlarged scale;

Fig. 9 is a plan showing the application of this invention to a different type of skate;

Fig. 10 is a side view of the same;

Fig. l1 is a plan of the front part of the heel iece;

Fig. piece;

Fig. 13 is a sectional of Fig. 9, and

l2 is a plan of the rear part of the toe view on the line |3-l3 Fig. 14 is a. sectional View on the line I4-I4 of Fig. 9.

The end pieces of the roller or ice skate oomprise a toe piece i0 and heel piece il, each provided with mountings l2 and I3 respectively for receiving the rollers, which are not shown. In the rst sheet of drawings the end pieces are both provided with longitudinal flat grooves Iii and I5 respectively on top making, of course, corresponding at projections i9 on the bottom with slanting sides. These grooves I4 and l5 are wide and shallow and they are provided with corrugations or square edged teeth Il, which are formed, as sho-wn in Fig. 8, by a die pressing or punching process which brings a series of parallel teeth to the top and bottom respectively of the sheet metal of which the toe piece and heel piece are made. In each case this shallow groove is provided with a square or other non-circular perforation I8.

The shank piece 20 is formed of sheet metal having a central anges 2i, which are bent around in the form of hollow substantially cylindrical beads extending therealong. These beads serve two purposes. First, they strengthen the shank piece, which is formed of a relatively light sheet metal, against bending in a longitudinal direction, and second, these beads serve as side walls to come against the walls of the projections I6 of the end pieces le and Il. This prevents shifting sideways of the connected parts.

The shank piece is provided with two slots 22 and 23 longitudinally placed and spaced apart and is also provided with `square edged teeth 24 on the bottom and top like the teeth Il and formed in the same way. These teeth serve two parts together in rm relationship and second, to strengthen the shank piece against bending in a transverse direction. The shank piece 20 can be adjusted to project from the rear of the heel piece as far as desired, so it allows a wide range of adjustment.

To hold these three parts together a pair of bolts 25 and 26 are employed extending through the square holes I3 and the slot 22 or 23. On the under side each bolt is provided with a nut 27 and a washer 28. The parts are adjusted to the position shown to provide a skate of the desired length and the nuts are screwed up to hold the three parts together. As the washer and the head of the bolt both engage the corrugated surfaces the nuts can be tightened up rmly and will hold the parts together in a strong and permanent manner.

The provision of the beaded sides of the shank piece 2i) tting the slanting walls on the projections of the bottom of the heel pieceand toe piece further prevents displacement of the parts. Even if the nuts become loosened a little, they will keep the parts in proper relationship for a time. The shank piece is made strong in both directions by the beads and corrugations without increasing the amount of metal in it or the expense of manufacture. It also is so constructed on account of the corrugations as to facilitate adjustment and the tightening of the parts after adjustment. This constitutes asimple and inexpensive skate having improved strength and increased ability to plane portion and provided with withstand twisting strains without displacing the toe piece or the heel piece from the shank.

In the form shown in the second sheet of drawings, certain features of this invention are shown as applied to another type of roller skate in which the toe piece and heel piece 3| are provided respectively with projections or tongues 32 and 33, the former having a slot 34 and the latter a perforation 35a for fastening bolts 3B, These projections 32 and 33 overlap each other and they are provided with the same kind of corrugations or teeth 35 as have been described. The toe piece is slightly slanted at 35 and provided with a slot 31 through which the end of the tongue 33 can pass. The end of the tongue 33 is provided with an open-ended slot 38 so that the two parts can be adjusted close together and the end can pass beyond the stationary guard 39 for the adjusting screw 4B.

The sides of the toe piece are bent over downwardly to form heads 4I located entirely below the upper surface thereof. This may extend any desired distance and preferably extends through*- out the straight sides of this member. The beads constitute means for strengthening it because it cannot be strengthened by a longitudinali-ib in the center very readily on account of the teeth or corrugations. The functions of the new features in this form of the invention are substantially the same as those described in connection with Sheet l of the drawings.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details disclosed, otherwise than as set forth in the claims, but what I claim iszl. As an article of manufacture, a shank piece for a skate consisting of a sheet metal piece having its longitudinal edges in the form of hollow substantially cylindrical beads extending the length of the shank piece.

2. As an article of manufacture, a shank piece for a skate consisting of a sheet metal piece having its longitudinal edges in the form of hollow substantially cylindrical beads and transverse square edged corrugations on the top and bottom surfaces, extending from one bead to the other, the shank piece having two separated longitudinal slots for receiving fastening devices.
